MAGAZINE TACK HAMMER.

Application led April 12, 1924. Serial No. 706,068.

To all whom. it may concern:

Be it known that I, IVILLIAM H. BOOTH, a citizen of the United States, residing at Baton Rouge, in the parish of East Baton Rouge and State of Louisiana, have 1nvented certain new and useful Improvements in a Magazine Tack Hammer, of which the following is a specification.

This invention relates to improvements 1n magazine hammers.

The primary object of the invention is the provision of a magazine hammer embodying novel means for feeding tacks from a supply container within the hammer to a driving head, in a positive and eiliclent manner, so that the hammer may be usedrln any position, nothing being dependent upon fo-rce of gravity to prevent use of the hammer in various positions.

A further object of this invention is the provision of novel dispensing means for feeding of tacks from a supply source to the driving head of a hammer.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Fig. 7 is a cross sectional view taken through the tack hammer substantially on the' line 7-7 of Figure 2.

Fig. 8 is a fragmentary cross sectionall view taken substantially on the line 8-8 of Figure 7, and showing more particularly novel dispensing features of the tack hammer, and

Fig.- 9 is aI cross sectional view taken through the handleof the tack hammer, showing a novel channel or track Way therein for the conveying of the tacks from a supply source to a dispensing mechanism, this view being taken substantially on the line 9-9 of Figure 1.

In the drawings, wherein for the purpose of illustration is shown only the preferred embodiment of the improved magazine tack hammer, the letter A may generally designate this hammer, which ma consist of a handle structure B; driving ead construction C; track way D; dispensing means E;

and a carriage F for conveyin tacks from the dispensing means E to the riving point on the head construction C.

The handle B is preferably hollow, providing the compartment 10 therein along which the track way D extends. In the handle grasping portion of the handle B, a tack container 1l may be positioned, which opens through the. rear end of the handle B, and is normally closed by a cap 12 which may be removed for the purpose of placing a supply of tacks in the container 11.

The track D is preferably of channel shaped format-ion, providing a slot or way 13 extending longitudinally thereof, which is to receive the head portions of the tacks, and the track D is provided with a slot 14 in the bottom thereof through which the shanks of the tacks depend as the tacks are moved along the track way D toward the dispensing mechanism E.

The driver head 'construction C' of the hammer preferably includes a substantially cylindrical shaped casing 16, which is formed rigid at the forward end of the handle B. This casing 16 provides a compartment 17 therein which receives the main portion 18 of the driver head construction. This portion 18 is of bifurcated substantially cylindrical shaped formation, and at its upper end this member 18 is formed integral with a detachable cap 19 which may Vbe screw threaded in the upper end of the casing 16, so that it may be readily removed from the compartment of the casing 16. The mainbody portion 18 is, in fact, a

v are adapted to cooperate in tripping a tack vus placing finger 32, as will be subsequently described. The lower surface 33 of the driver head part 18 is adapted to receive the head of the tack thereon, so that it may be held in position by magnetism, to permlt the driving of the tack.

and

v on the upper wallv thereof Referrin to the dispensing mechanism E which is a apted to place the tack u on the carriage F so that it can be conveye to the surface 33 of the driver head part 18, the same includes a slide casing 40, which is slida-bly disposed on the track way D, and

receives the latter in a suitable opening provided longitudinally therethrough. The track way D, at its forward end, is slotted as at 41, and a spring 42 is fixedly carried by the upper wall of the track way D, at the extreme forward end of the track Way, the spring having the free end thereof depending into the area along whiclrthe heads of the tack travel, so as toretard travel of the tacks. Thesliding part 40 of the dispensin mechanism E pivotally carries a'pawl or ispensing arm 43, which is urgedby spring 44, so that the free end 45 of the same extends beneath the track way D,`immediately below the slot in the trac way, so that the free end of this arm 43 may engage the shank of the foremost tack, ush theV tack forward in the track way l), as the slide part 40 is moved forward, for the purpose of moving the foremost tack past the retarding spring 42, and onto the carriage mechanism F, when the latter is positioned as is illustrated in Figure 3 of the drawings. The rear surface 48.

at the free end of the dispensing arm 43 is rounded, so that the arm may readily flex or move ast the shank of the foremost tack, as the sllde 40 is moved to the rear along the handle, after a dispensing operation has been effected. A spiral spring-49 is preferably carried by the fixed casing portion 50, one end of the-spring 49 being held by a stationary pin 51, and the opposite end of the -s 4rin being engaged by a lug 52 formed on t e sidin part 40 of the dispensing mechanism; t e function of the spring 49 being to push the slide 40 rearwardly after a dispenslng operation has taken place, to posit-lon the arm 43 rearwardly of the shank of a foremost tack, so that the dispensing mechanism is in position for another operation. The casing portion 50 is welded` or K,consists mainly of Ithe tubular of upstanding attaching arms and 61 of the slide 40; a pin being carried by these arms 60 and 61, which extends throu h a slot 63 provided in the bell crank en 59.

The other end portion 65 of the bell crank extends for o 4ration by a pivoted lug-or fin er 68 of t e carriage mechanismA F, as wi be subsequently described.

Referring to the .carriage mechanism F, the same is mounted for travel longitudinally of the driving head construction C, and

having the passa eway 71 therein for slidably receiving t e lmain part 18 of the driving head. The tubular portion is slidably disposed through an opening 72 in the lower wall ofthe driving head casing portion 70,

16 so that the same may extend outwardly vof thev driving Ahead construction C.` Inwardly of the compartment 17, thel tubular ,portion 70 of the 'carriage is provided with a flange 75, and a spiral actuating spring 77 is placed about the main part 18 of the driving head, and at vone end engages the cap 19, and at its other end engages the inner end of' the tubular portion 70 of the carriage F, to force said tubular portionI outwardly from theA driving head, in the position illustrated in Figlire 2 of the draw- ,"2

1ngs. The tubular portion 70, at its upper end, and within the driver head casing 16, Su ports the spaced arms ,80 and 81, provi ing a slot 82 therebetween. In th1s slot 82, the tri member 32 is pivoted, as by a pin 84, and this tri member 32 has a lu'g end 85 which norma ly extends into the slot 30, between the spaced leg portions 25 and 26 of the driver head part 18. The trip member of trip arm also has a spring 88 which normally acts to push the lug 85 into the slotted way 30, and to move the free end of the trip member 32 against the head of a tack after the same is received in the transverse Way 90 of the carria e mechanism. The lug or finger 68 pivota ly carried by the carriage mechanism F, within the com artment of the driver head casing 16, is aced upwardly of the trip member 32, an suported in the slot 82 by a pin 92. This linger 68 may move upward from itspivot pin 92, but a pin 93 is placed so that the finger 68 cannot move downwardl and a spring 94 normally urges the nger 68 against the stop pin 93, yso that it is in position for operating the dispensing mechanism, as will be subsequently described.

In opera-tion, the'tacks will be fed along the channel shaped track way D, incident to natural movement of the hammer during u. tack driving operation. The tacks will iiiove along this track way D, and at the forward eiid of the track way D the tacks are retarded in their further movement by ineaiis of the retarding spi-ing 42.' The blow for the driving operation sends the carriage F upwardly in the. casing 16, along the driver head part 18, so that the tac which is supported upon the lower end of the magiiet'is driven; the carriage being adapted to move entirely upwardly in the casing 16, into the position illustrated in Figure 3 of the drawings, to expose the tack so that it may be driven. This upward movement of the carriage F iii the driver head causes the laterally extending finger or lug 68 to engage the portion 65 of the bell crank lever 58, and will rock the `bell crank lever 58 into the position illustrated in Figure 3. This will cause the sliding part 40 of the dispensing mechanism E to move forwardly along the track way D, and the free end 45 of the dispensing arm 13, engaging rearwardly of the shank of the foremost tack, will shove this foremost tack forwardly pastvthe retarding spring 42, and the head of this tack will enter the transverse passage 90 vin the carriage F. When the blow has been completed and as the driver head is being lifted, the spring 77 will assert itself and force, the carriage F outwardly from the driving head. This will cause the nger `68 to move out of operating relation with the bell crank 58 of the dispensing mechanism E, and the spring 49 of the dispensing mechanism E will operate to cause the slide 40 to move rearwardly along the trackway, so that the dispensing arm 43 will be-positioned rearwardly of the shank of the foremost tMik, in the position illustrated in Figures 2 and 8 of the drawings. It is to be noted, that when the carriage F moves to its uppermost position within the casing 16, the lug 85 of the trip member 32 engages the upper end of the slot 30, and causes this trip member 32 to move out of obstructing relation with the transverse passageway 90, so that the dispensing mechanism can properly insert the foremost tack into carrying relation on the carriage F. However, upon the downward movement` of the carriage mechanism, the spring 88 will cause the trip member 32 to move into engaging relation with the head4` of the tack which is carried by the carriage F, and when the carriage mechanism F has reached its outermost position with respect to the driving head C, the tack head will not rest against the main part 18 of the driving head structure, so that the spring operated trip 32 will force the tack onto the supporting surface 33 of the magnet, and will thus position the tack as illustrated in Figure 2 of the drawings, so that it is ready to be driven.

From the foregoing description of this invention it is apparent that a novel prin- .ciple of operation for magazine hammers the location of the hammer, nor the cn-y vironnient in which it may be used.
